Please correct your my grammer

I try to be a stickler when it comes to the usage of grammar and spelling.

But whenever I am writing something I just tend to let my fingers fly on the keyboard. Alright, alright. It’s more like I let my fingers waddle on the keyboard.

That said, I tend to make grammar errors. Spelling not so much. My Mac tends to put red squiggly lines under each misspelled word. But grammar is my weak point. I hope I don’t make that too many mistakes.
